The purpose of this paper is to analyze theoretically and empirically spillover effects of fishery quota on related markets through their demand curves. Theoretically, the spillover effects of a change in quota can be captured through the directly distorted market alone by computing surpluses associated with the new and old equilibrium. This study estimates empirically demand functions in the context of both the partial equilibrium and general equilibrium. The spillover effect can be computed from the difference between these two estimates. The econometric methodology to estimate the demand curves in the context of general equilibrium is presented and illustrated. The empirical result of fishery markets shows that spillover effects transmitted across other markets are not small and approximately account for 43.3% of the partial equilibrium welfare effects.

The aim of this study was to compare medical cost of hospice care and that of conventional care during the last year of life, and identify factors that influenced the cost. From January to August 2003 592 terminal cancer patients receiving care from 5 hospice care units and 2 hospice care teams in general hospitals were enrolled to case group. Two hundreds and seventy two terminal cancer patients receiving conventional care from 7 general hospitals were enrolled to hospital-based control group, and 1,636 terminal cancer patients from 122 general hospitals located in same regions with the 7 hospitals were enrolled to community-based control. We used characteristics and medical cost from data of National Health Insurance Cooperation. Total medical cost per beneficiary in cases was about 10 millions won, 14.5 millions in hospital-based controls and 11.1 millions in community-based controls. The hospice care saved $45\%$ over the last year of life compared with hospital-based controls (p<0.0001). Saving of inpatient cost account for approximately $80\%$ of saving per beneficiary. Hospice care saved $29\%$ of medical cost per hospitalization day compared with hospital­based controls and $17\%$ compared with community-based controls (p<0.0001). Multiple regression analyses showed that hospice care significantly saved the medical cost. This study suggest that hospice care save medical cost compared with hospital-based control and community-based control. Most of saving of inpatient cost account for approximately $80\%$ of saving of medical cost.

The purpose of this paper is to analyze vowel lengthening triggered by resyllabification. In general, short vowels become long when a following consonant is deleted, as shown in stehli 'steel' > st$\bar{e}$li and *fimf 'five' > five. We can account for the phenomenon in a straightforward way within the framework of CV phonology (Clements & Keyser, 1983) : deletion of a coda consonant C slot and then the preceding vowel spreads onto it, resulting in a long vowel. The analysis, however, cannot hold for words like ealhes 'temple', where deletion of an onset segment eventually triggers vowel lengthening in the preceding syllable. In order to account for this, I propose resyllabification. That is, ealhes first becomes eales by /h/-deletion. Next, the /l/ in coda is resyllabified as the onset of the following syllable, leaving its C slot unoccupied. Finally, the vowel spreads onto the empty slot, producing a long vowel.

This paper aims to provide an account for the English anaphors under the framework of the recent development of minimalism (Chomsky 1999, 2001). I propose that the anaphor has the uninterpretable [a] feature. The Agree operation erases the [a] feature by feature match. Once the [a] is deleted, the derivation converges, providing a proper interpretation of the anaphor. When there is no matching phi-features, the [a] cannot be eliminated, inducing the derivation to crash. The Agree operation can account for not only the typical local binding cases in English but the apparent long-distance binding cases in the picture-DP and expletive constructions. Consequently, the traditional concept of the binding domain and dichotomy between local and long-distance types are abandoned in favor of the analysis under the framework of minimalism. The minimalist accounts thus maximally simplifies the binding principles, using the general operation Agree only.

The calculation method which takes into account the shear lag effects on the ultimate transverse bending moment of a SWATH(Small Waterplane Area Twin Hull) ship has been developed. In case of the ultimate bending strength analysis of conventional monohull ships and general box girder structures, the hypothesis that plane section remains plane after bending can be employed but not in the case of the structures having wide flange. For the ultimate bending strength analysis of such structures, a new method which can take into account the effect of shear lag on the ultimate bending strength has been developed by adopting more reasonable assumption that warping distortion of the section takes place inthe same way as the actual stress distribution. Finally, the proposed method has been applied to a a SWATH cross deck structure.

Using the simulated data set which is based upon the data set merging Economically Active Population Survey(EAPS) and the Supplementary Survey (SS) in 1998-2001, this paper examines the relevance of alternative programs Unemployment Insurance Savings Account (UISA) and Pension-funded Unemployment Benefit (PUB) - to unemployment insurance system in Korea. Estimating the relative size of unemployment benefit and IA balance under a specific type of UISA or PUB by simulation, this paper yields the two main results. First, replacing UI by UISA with the same benefit being maintained would be beneficial in terms of search efficiency in general, although its effectiveness is a little doubtful as for the non-regular workers. Second, the PUB is better than UISA as an alternative to UI, and also works relatively well even for the non-regular workers.

There is a general challenge offered to the field of engineering economics by the introduction of advanced technologies. A survey of the existing literature on evaluation of advanced information and manufacturing system indicate that the traditional approaches are inadequate for economic evaluation techniques used in its appraisal, difficulty in evaluating the potential benefits and criteria used to assess management performance. In this paper, an attempt has been made to overcome the above deficiencies by presenting an approach to account for the justification and selection of the Local Area Network(LAN) architectures. This is based on the Analytic Hierarchy Process(AHP) and is capable of taking into account many intangible factors as well. The usefulness of the proposed approach is demonstrated through a case situation and sensitivity analysis. Finally, some research directions for future work are identified.

The temporal structure of events on the discourse level has long been of great interest in both theoretical and computational linguistics. In this paper, we offer a unified approach to the temporal relationships related to a hierarchical discourse structure. We apply the method of pronoun resolution to the interpretation of tense. It is based on an analysis within the framework of the controlled information packaging theory. A unique aspect of our account is that temporal interpretation across discourse segments in global discourse is subject to the same principles as the interpretation of global anaphora, and that there is thus no need to postulate independent principles to account for the discourse behaviour of tense. In this way, we can neatly explain the general view that tense parallels the anaphoric nature of pronouns.

The probabilistic tsunami risk assessment of large coastal areas is challenging because the inland propagation of a tsunami wave requires an accurate numerical model that takes into account the interaction between the ground, the infrastructures, and the wave itself. Classic mesh-based methods face many challenges in the propagation of a tsunami wave inland due to their ever-moving boundary conditions. In alternative, mesh-less based methods can be used, but they require too much computational power in the far-field. This study proposes a hybrid approach. A mesh-based method propagates the tsunami wave from the far-field to the near-field, where the influence of the sea floor is negligible, and a mesh-less based method, smooth particle hydrodynamic, propagates the wave onto the coast and inland, and takes into account the wave structure interaction. Nowadays, this can be done because the advent of general purpose GPUs made mesh-less methods computationally affordable. The method is used to simulate the inland propagation of the 2004 Indian Ocean tsunami off the coast of Indonesia.
